Descripcion de la invencion.Description of the invention.
Para solventar los problemas mencionados se ha ideado el sistema de production de agua caliente sanitaria con energia solar objeto de esta invencion que presenta unas particularidades constructivas orientadas a conseguir la produccion de agua caliente sanitaria de una forma economica, sostenible, fiable, segura y mediante una facil instalacion; evitando los problemas mencionados anteriormente, tanto en lo que se refiere al sobrepeso de las placas a instalar sobre el tejado o cubierta, al ruido de la circulation del agua por el interior de los tubos y a la utilization de largos recorridos de tubo para el transporte de agua caliente desde las placas del techo hasta los puntos de consumo.To solve the aforementioned problems, the system of production of sanitary hot water with solar energy has been devised, object of this invention that presents constructive particularities oriented to achieve the production of sanitary hot water in an economical, sustainable, reliable, safe and through a easy installation; avoiding the aforementioned problems, both as regards the overweight of the plates to be installed on the roof or deck, the noise of the circulation of water inside the tubes and the use of long tube paths for the transport of hot water from the ceiling plates to the points of consumption.
Para conseguir estos objetivos el sistema para la produccion de agua caliente sanitaria con energia solar objeto de esta invencion comprende un termo electrico provisto de una entrada de agua a temperatura ambiente y de una salida de agua caliente sanitaria provista de una valvula termostatica, adecuada para controlar la temperatura maxima de salida del agua caliente sanitaria; y un numero variable de placas fotovoltaicas para la alimentation electrica del termo electrico modificado.To achieve these objectives, the system for the production of sanitary hot water with solar energy object of this invention comprises an electric thermostat provided with a water inlet at room temperature and a domestic hot water outlet provided with a thermostatic valve, suitable for controlling the maximum outlet temperature of domestic hot water; and a variable number of photovoltaic panels for the electrical supply of the modified electric thermos.
En una realization de la invencion estas placas fotovoltaicas pueden encontrarse conectadas en serie, por medio de un magnetotermico de entrada, a una electronica de control integrada en el propio termo electrico modificado.In an embodiment of the invention these photovoltaic panels can be connected in series, by means of an input magnetothermal, to a control electronics integrated in the modified electric thermos itself.
Esta constitution del sistema objeto de la invencion permite utilizar placas fotovoltaicas en vez de placas solares termicas para la captation de la energia solar, conectandose las mencionadas placas fotovoltaicas al termo electrico, lo que resulta mucho mas economico y sencillo que realizar largas tiradas de tubos de agua para la conduction de agua caliente desde las placas solares termicas utilizadas habitualmente hasta los puntos de consumo.This constitution of the system object of the invention allows the use of photovoltaic panels instead of thermal solar panels for the capture of solar energy, the said photovoltaic panels being connected to the electric thermos, which is much more economical and simple than making long runs of tubes water for the conduction of hot water from the thermal solar panels commonly used to the points of consumption.
Preferentemente el termo electrico se encontrara dispuesto en una zona proxima a los puntos de consumo, lo que permite reducir notablemente las perdidas de calor en los tubos de conduccion de agua respecto a las instalaciones con placas termicas solares.Preferably, the thermoelectric heater will be arranged in an area close to the points of consumption, which makes it possible to significantly reduce heat losses in the water conduit pipes with respect to installations with solar thermal panels.
Dado que en la solution de la invencion la conexion entre las placas fotovoltaicas y el termo electrico se realiza unicamente mediante cables electricos, tambien se elimina el ruido producido por la circulacion del agua en las instalaciones de placas termicas solares.Since in the solution of the invention the connection between the photovoltaic panels and the thermoelectric is made only by electric cables, the noise produced by the circulation of water in solar thermal plate installations is also eliminated.
De acuerdo con la invencion la salida de agua caliente sanitaria procedente del termo electrico dispone de unos ramales de conexion a una caldera de calefaccion y una llave de paso adecuada para conectar los puntos de consumo de agua caliente sanitaria con la salida de agua caliente procedente del termo, bien directamente o bien a traves de la mencionada caldera de calefaccion.In accordance with the invention, the domestic hot water outlet from the electric heater has connection branches to a heating boiler and a suitable stopcock to connect the points of domestic hot water consumption with the hot water outlet from the thermo, either directly or through said heating boiler.
Dichos ramales permiten conectar eventualmente la salida de agua caliente sanitaria procedente del termo electrico con un circuito de calefaccion para su alimentacion.Said branches allow the connection of the domestic hot water outlet from the electric heater with a heating circuit for its supply.
Esta caldera de calefaccion, de uso opcional en el sistema de la invencion, actua como elemento de apoyo para subir la temperatura del agua caliente sanitaria proporcionada por el termo electrico cuando esta es insuficiente.This heating boiler, optional for use in the system of the invention, acts as a support element for raising the temperature of the domestic hot water provided by the electric heater when it is insufficient.
En la invencion tambien se ha contemplado que agua caliente procedente del termo electrico pueda utilizarse para alimentar un circuito de calefaccion, reduciendo el consumo de la caldera destinado a calefaccion.In the invention it has also been contemplated that hot water from the electric heater can be used to power a heating circuit, reducing the consumption of the boiler for heating.
